To @ZZ wwnt it 71mg/ concern:

Beit known that I, GEORGE E. HUGULEY, a citizen of the United States, and a resident of Atlanta, in the county or Fulton and State of Georgia, have invented a new and lmproved Vehicle-Tire, of which the following is a full, clear, and exact description.

The purpose otl the invention is to provide a supplemental tread section for the outer vtubes of pneumatic tires, or any rubber tire used upon the 'Wheels of automobiles or similar heavy vehicles, --Which supplement al tread section can be quickly, conveniently and firmly applied.

A 'further purpose of the invention is to so construct said supplemental tread section that it will add materially to the resiliency of Ithe tire te 'Which it is applied, and so that the 'fastening devices will not detract from said resiliency; and also to so construct the supplemental tread section that it will render the outer tube comparatively punctureless at the tread and so that should the supplemental section become unduly Worn or damaged it can be removed and replaced by another Without damage to the main tire.

The invention consists in the novel construction and combination of the several parts. as will be hereinafter fully set forth and pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the iigures.

Figure 1 is a transverse section through a portion of the outer tube of a vehicle tire and through the supplemental tread section applied; Fig. 2 is an enlarged circumferential sectional side view through a portion of the supplemental tread section of the tire and the outer tire and` Fig. 3 is a plan view of the keeper device carried by the outer tire and constituting a portion ol' the locking mechanism employed to connect the main and supplemental tires.

A represents the outer tube of the pneumatic tire, which tube is provided with a flat tread section and With a circumferential Wall 11 at each side orl the tread section, forming thereby a tread channel 12. A strip 14 of raw-hide is made to lie close upon the bottom Wall of the tread channel 12 as is shown in Figs. 1 and 2,' and the said strip extends from one side Wall of said channel, and in this channel 12 a keeper device B is secured, which device as is shownfin Fig. 3,

consists of parallel rods 15 of Wire of suitable gage, connected at suitable intervals by transverse plates 16. When the outer tube A is molded the -wires or rods 15 are molded in the Walls 11 of the tread channel 12, the plates 16 extending from one side Wall oi the channel to the other as shown best in Fig. 1, constituting a series of keeper plates which maybe at any suitable distance apart.

C represents the supplemental tread section of the tire. This tread section extends entirely around the tube A and is provided with side flanges 17 which rest upon the Walls 11 of the tread channel 12 as is shown in Fig. 1. This supplemental tread section C extends any desired distance beyond the outer iace of the walls 11 of said tread channel 12 and enters said channel, the inner face of said supplemental tread section C being` made to bear against the rawhide strip 14, as shown best in Fig. 2. In the inner face of the supplemental tread section, a series of recesses 18 is produced, which recesses are spaced apart correspondingly to the keeper plates 16 in the channel 12 of the outer tube A, since when the supplemental tread section C is placed in position upon the outer tube A a keeper plate 16 will be received in each recess 18 of said supplemental tread section as is shown-in Fig. 2.

At each recess 18 in the supplemental tread section C a latch is employed. vThis latch consists of a shank 19 preferably in the form ot a flat plate as shown in Fig. 2, Which shank extends through the end Wall of a recess 18 and is vulcanized in the body portion of said supplemental tread section g -and a flat foot member 2O which is connected with the shank 19 by a connecting member 21 at right angles to said foot member and shank. The connecting member 21 extends down along the end Wall of the recess 18 at Which tl.. latch is applied, and the foot member extends circumferentially. Within the recess 18 ,z the length of the said connecting member 2 1 is such that When the supplemental tread section C is placed in position in the channel 12 of the outer tube A the foot members 2O of IOO all of the latches can be slid under the keeper 1o 5 In order to prevent the passage of pins or ilo sharp instruments through the segmental tread section C and into the outer tube A,

armor plates 22 are placed in engagement with the inner Vlace of the segmental tread section C, as shown in Fig. 2 by bearing upon the outer Vface o'lirthe rawhide strip 14; and 5 each armor plate 22 at one end is .introduced a comparatively short distance into the body of the supplemental tread section (l, beine` vulcanizedtherein. The rawhide strip 14- prevents any tendency on the part ol'V the exposed portions ol the armor plates 22 and the lioot members o'lt the latches possibly wearing' the outer 'tace olf the outer tube A. s The supplemental tread section (l adds `greatly to the strength of. a tire and further adds to its resiliency. The attachment as here made does not detract lfrom said resiliency and yet it a'l'l'ords a secure connection between the outer tube and the supiilemental tread.

It is obvious that when necessary the supplemental tread section (l can be quickly and conveniently removed and substituted by another il so desired. 't is Yfurtherniore evident that the supplemental tread section t does not in any manner interfere with the inner or in'llated tube when such is employed.

Having thus described my invention, l. claim as new, and des-ire to secure by Letters Patent,-

1. In vehicle tires, an outer tube having' an exterior annular channel at its tread portion, transversely extending),l d pers secured in said cliaiinel at a distance Vfrom its bottom wall, a supplei'nental tread section adapted to cover and to enter the said channel, and latches located at the `inner Vlace of the said tread section. and arranged te pass between the said keepers and the bottom wall ot the said channel.

2. ln a vehicle tire, an outer tube section provided with a peripheral annular channel at its tread, keeper plates extending' from side to side of said channel and secured to the said tube, the keeper plates being spaced Vfrom the bottom wall ol" the channel,a supplemental tread section which covers the said channel and extends therein, said supplemental tread section being provided with a series ot recesses in its inner lace, the distance between the recesses corresptmding,l "fistantially to the distance between the keeper plates in said. channel, a latch located. at an end. side wall oil. cach recess, which latches are secured to the supplemental tread section, said latches being' adapted to pass beneath the keeper plates, and a protective strip located upon the bottom wall of the sa id tread channel on the outer tube, against which protective strip the said latches havr bearing.

ln a vehicle tire, an outer tube provided with a peripheral annular channel at its tread, wires vulcanized in the side walls et said channel, keeper plates secured. to the wires and extending; trom one wall to the other, crossingY the said channel, a supple mental tread section extending into said channel and beyond the outer lace ol'V the said outer tube, protective plates engagingI with the inner Vlace ol'` the supplemental tread seetion, which plates have an end secured in the said supplemental tread section, and laici es located at the inner side portions oll the said supplemental tread section, to pass beneath the keeper plates in the channel olt the outer tube.

el, ln a vehicle tire, an outer tube provided in its tread with an annular channel and harn ing keepers extending, trai'isversely oll the channel and spaced lirom the bottom lhrreol'. and a suppleincntal tread section extending.' into the chz'umel, said supplemental tread section beinel providedv in its .inner hice wir h recesses correspondnur in number to the keepers ol" the channel and with latches proY jecting into the recesses with their lower laces 'lush with the inner liace ol'V the supplemental tread and extendingl beneath the keepers in the cl'iannel ol'A the outer tube.

5. ln a vehicle tire, an outer tube provided .in its tread with an annular channel, wires vulcanized in the walls of the channel and connected by plates, said plates evteiidingr across the channel and spaced lrom the bot tom thereof, a supplemental tread sect ion rxtending into the channel and provided on its inner Vlince with 'recesses eorrespondinjgj in number to the plates in the channel` and latches vulcanized in the supplemental t read section and projecting;i into thtl recesses thereof with their lowerliaces l'lush with the inner 'liace o'lE the supplemental tread and exreiidiiig.;l beneath the plates in the channel olI the outer tube.
